WATCHMANS TlME DETECTOFL SPECIFICATION forming part of Letters PatentNo. 698,862, dated April 29, 1902*.

Application filed November 25,1901. $erial No,f83,555. (No model.)

To all whom it may concern:

Be it known that I, J AKOB SOHLENKER, of Schwenningen, in the Kingdom ofWiirtemberg and Empire of Germany, have invented certain new and usefulImprovements in Watchmens Time-Detectors, of which the following is aspecification.

This invention relates to a Watchmans time-detector, and has for itsobject topro- Vide certain improvements in the same.

The invention consists of a watchmans time-detector comprising arotatable timedisk, at marking-plate having matrices provided thereon.and capable of lateral move ment, a key cooperating means carried bysaid marking-plate, and marking-keys cooperating with said means andhaving markingtypes on their end faces, as will be more fully describedhereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a rear elevation of myimproved watchmans time-detector with the cover'in open position. Fig. 2is a Vertical transverse section on line 2 2, Fig. 1, the cover beingclosed and a key being inserted in the device. Fig. 3 is a detail rearelevation showing the marking-plate and a portion of the graduatedtime-disk.-

Fig. t is a detail bottom View of Fig. 3. Fig. 5is a detail showing thedifferent shapes of keys, and Fig. 6 is an inside View of themarking-plate.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a represents a disk, which is rotated on itsaxis by a clockmovement of any approved construction, which is locatedin the "main portion of the casing D. On the disk a is placed a paperdisk 6, provided with the usual time-indicating graduation. A lever O issuspended in the nature of a pendulum from a pin 0 on thepartition-plate D and is held by a notched spring (1, engaging a stud din a central position. The lower end of the pendulum O carries aguide-roller e, which is located in an enlarged T-shaped portion of thekeyhole 6, into which the marking-keys are inserted. The lower swingingend of the pendulum-lever 0 carries a plate f, in which are engraved orstamped matrices f in different relative positions. These matrices arelocated in the center line of the plate and at either side of saidcenter line. On the end faces of the marking-keys, which are located inthe controlling-boxes at the different stations, are arranged types 15at different heights of the end faces, so as to correspond with therelative positions of the matrices on the plate f of the pendulum-lever0. Some of the marking-keys K are provided with side projections K ofgreater or lesser lengths and others withnone, so that when a key isinserted into the keyhole of the casing of the time-detector the sideprojection or rib on the key abuts against the roller 6 of thependulum-lever and moves the same toward the right or left or imparts nomovement to it when the key has no side projection or rib. The lateralmovement of the pendulum-lever toward one side or the other isnecessary, so as to bring the marking-type on the end face of the keyand the corresponding matrix on one side or the other of the center lineof the platef in coincident position toward each other, so that by acomparatively light pressure on the key a visible mark is produced onthe time-disk b, which is located between the type and plate f.

The watchman is controlled by the timedetector in the following manner:When on his beats, he has to appear at a certain time at a determinedplace. He then takes the marking-key from the box and inserts it intothe keyhole of the casing of the time-detector carried by him. The sideprojection or rib on the key produces such a lateral movement of thependulum-lever that the matrix on the marking-plate of thependulum-lever coinciding with the marking-type on the end of the keyproduces by a slight pressure of the key on the time-disk the propermarking corresponding to the number of his box. The markings areproduced in such positions on the graduated scale of the time-disk as toindicate the time at which they are impressed on the same and the numberof boxes visited by the watchman. Alarger number of markings can be madeby the improved time-detector than by the detectors heretofore in use.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a watchmans time-detector, the combination of arotatable time-disk,with a marking-plate, having matrices providedthereon and capable of lateral movement, a key cooperatin g meanscarried by said marking-plate, and marking keys cooperating with saidmeans and having marking-types on their end faces, substantially as setforth.

2. In a Watchmans time-detector, the combination of a marking-plateadapted to have lateral movement and having matrices provided thereon,with marking-keys provided with means for laterally moving saidmarking-plate and cooperating with said matrices, substantially as setforth.

In a Watchmans time-detector, the combination of a rotatable time-disk,with a laterally-movable marking-plate arranged at one side thereof andhaving matrices provided thereon, a keyhole, a key cooperating meansarranged in line with said keyhole and carried by said marking-plate,and marking-keys adapted to engage said means and impressing saidtime-disk from the side opposite to said marking-plate, substantially asset forth.

4. In a Watchmans time-detector, the combination of a marking-platecapable of lateral movement and having matrices provided on the centerline thereof and at each side of said center line, with a roller carriedby said marking-plate, and a marking-key, having a side rib with aninclined surface, adapted to engage with said roller for moving saidmarking-plate, and having a marking-type on the end face thereof,substantially as set forth.

5. A watchmans tin1e-detector, comprising a graduated time-disk rotatedby a clockmovement, a pendulum-lever, a spring for holding saidpendulum-lever in central post tion, a marking-plate provided withmatrices mounted on the free or swinging end of said lever, a rollermounted on said lever in line with the center of the marking-plate andkeyhole, and a plurality of keys provided with projections or ribs onthe sides and markingtypes on the end faces, substantially as set forth.

6. A watchmans time-detector, comprising a graduated rotary time-disk, aspring-controlled pendulum-lever suspended at one end and having anenlarged opening at the free opposite end, a marking-plate provided withmatrices mounted on the free end of said lever, a roller supported infront of said plate on the free end of the lever, and a plurality ofkeys provided With side projections or ribs of greater orlesser lengthsand marking-types on their end faces, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
